CURTAlN-SHADE STRIP.

SPECIFICATION forming part of Letters Patent No. 591 ,389, dated October 12, 1897. Application iiled February 17, 1897: Serial No. 623,839. (No model.)

To all whom t may concern:

ings, and to the letters and gures of reference marked thereon.

My invention relates to an improvement in curtain-iixtures, and particularly to a win-j dow-shade strip having brackets in which the ends of the shade-roller are hung; and

my object is to provide a device which mayv be readily adjusted, accommodate different widths' of shades, which may be manufactured at a comparative slight cost, and which may be adjusted to the proper position by the purchaser or consumer, thus doing away with the necessity of employing skilled workmen to put the same into position.

The invention consists in the matters hereinafter described, and referred to in the appended claims.

In the'drawings which illustrate the invention, Figure 1 is a perspective View of my improved shade-strip. Fig. 2 is a vertical section on the upright line shown in Fig. 1.

In the drawings, A represents the curtainfixture as a whole, it being composed of the two correspondingly-formed parts B C. Both parts B and C are herein shown as formed of single pieces of metal With outwardly-extending brackets a l?, one of which has a slot and the other a hole forlthe reception of the ends of the curtain-roller c. The part Bis provided with the bead D, extending throughout its entire length, and it will be understood that any number of these beads may be provided. The part C is provided with a corresponding bead D. The bead D is adapted to fit in the groove formed by the striking up of the bead D on the part C, the nesting of these two beads forminga way on which the parts maybe guided and slipped one over the other."

To prevent displacement longitudinally and also to confine the parts together vertically, the part B at its inner end is provided with two narrow slits 1, the material 2 between these slits being raised above the adjacent portion of the part B, or this part 2 may be separated at one end from the body portion B, forming a tongue of metal. Beneath or behind the raised portion or tongue 2 pass the ends of a strip E of tin or other suitable material, these ends overlapping and being secured by forcing down the tongue or strip' 2 of metal, thus clamping said overlapping ends against the body of the strip B, this holding action being still further strengthened by the fact that the tongue or strip 2 is cut out of the bead or raised portion of the `part B, so that the overlapping ends of the clamp E are forced in against the grooved sides of the part B and are firmly wedged in position. The plain face of the clamp E passes around and embraces the part C, which is thus guided thereby as it slides back and forth on the strip B. The part C at its inner end has a portion of its bead cut away just wide enough to receive the plain face of the clamp F, which embraces the part C and at its ends passes partly around the strip B, which is guided thereby. By this arrangement it will be seen that the plain faces of the clamps E and F are in front, thus giving a neat appearanceto the device. Suitable openings e are provided on each part B C for the passage of nails or screws which are adapted to be driven therethrough to secure the strip in place when it has been adjusted the proper length. By making these two parts B C out of sheet metal and bending out the ends to form the brackets, it will readily be seen that the xture may be made at a minimum cost, and the beads, one fitting within the groove formed by the other', not only act to guide these parts one on the other, but serve to strengthen the strip vertically and render it practical for the purpose for which it is intended.

Various minor modifications and changes in the construction of this device may be made without departing from the spirit of myinvention.

' Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A window-shade strip comprising two parallel parts or members sliding upon each other, one of said parts having longitudinal slits and that portion of its material between IOC the slits struck up to forni a raised portion or tongue, and a clainp encircling said two ineinbers or portions and held in place under said tongue or raised portion; substantially as de scribed.

2. A window-shade strip comprising two parts, each having alongitudinalbead formed on its surface extending throughout thelength thereof and arranged to iit one upon the other, and guidingclamps, one for each of said parts, one of said parts being provided with a slit forming a tongue by which the overlapping ends of its clamp are irlnly secured; substantially as described.

3. A window-shade strip comprising two parts7 each having a longitudinal bead formed on its surface extending throughout the length thereof and arranged to fit one upon the other, and guiding-clamps, one for cach of said parts, one of said parts being provided with a slit forming a tongue by which the overlapping ends of its clamp are firmly secured, and the other part having its raised bead cut away sufliciently to receive the plain face of its clamp, the ends of said clamp embracing the other part; substantially as described.

In testimony whereof I aix my signature in presence of two witnesses.
